Protect Your Inspection Accuracy with Calibration Shims

Industrial painters, powder coaters, and quality inspectors rely on electronic gauges to measure paint depth. However, a gauge is only as accurate as its last calibration check. High-precision coating thickness shims (also called calibration foils) provide the ultimate solution to verify your instrument reads correctly before painting begins.

Why Quality Inspectors Depend on Calibration Foils

These thin plastic sheets simulate a specific paint thickness. They allow you to test your dry film thickness (DFT) gauge on the exact substrate material of your project.

Key benefits of using premium shims include:

• Micro-Level Precision: Manufacturers label each foil with its exact thickness in both mils and microns.

• Color-Coded Verification: Bright, distinct colors help technicians select the correct target value instantly during busy field shifts.

• Substrate Protection: Placing a shim over your blast-cleaned steel sample protects the delicate probe tip from rough anchor patterns.

• International Compliance: Using certified foils ensures your testing workflow meets strict ISO and SSPC standards.

Common Coating Thickness Ranges

Select a shim combination that matches the expected dry film thickness of your industrial coatings.

Foil Color	Thickness (Microns)	Thickness (Mils)
Purple	25 µm	1.0 mil
Blue	50 µm	2.0 mils
Green	125 µm	5.0 mils
Brown	250 µm	10.0 mils

Simple Steps for Flawless Gauge Calibration

To start, place the shim flat against an uncoated piece of your project metal. Next, press your gauge probe firmly onto the center of the foil sheet. If the digital screen matches the shim value, your instrument is ready for certified inspection work.

Pro Tip: Always discard wrinkled or scratched shims immediately, as surface damage will distort your calibration readings.
